FLORA: BROAKLAND: QUADRANT B



AVENA FATUA / WILD OAT

 

PROVENANCE/NATURAL RANGE: Central Asia.

NATIVE HABITAT: Not fully know but likely semi-arid environments.

CONTEMPORARY RANGE: Widespread; now found in most temperate regions of the world. Found in all areas of California except the Sonoran Desert.

FOUND WITHIN STUDY AREA: Growing within an unirrigated three-foot-wide median on Adeline Street.

LIKELY MEANS OF ARRIVAL TO STUDY AREA: Accidentally introduced to North America as a contaminant in crop seed and feed by early European settlers. By 1824 the plant had already established itself in California.



CENTRANTHUS RUBER / VALERIAN

 

PROVENANCE/NATURAL RANGE: Mediterranean Basin.

NATIVE HABITAT: Dry and rocky sites.

CONTEMPORARY RANGE: Original range, but now including the western US, and southern Australia.

FOUND WITHIN STUDY AREA: Crack between curb and unirrigated landscape median.

LIKELY MEANS OF ARRIVAL TO STUDY AREA: Brought to the US as an ornamental plant; present in California by the mid-20th century.



ERIGERON (CONYZA) BONARIENSIS / FLAX-LEAF FLEABANE

 

PROVENANCE/NATURAL RANGE: Central or South America; precise origin has not been determined.

NATIVE HABITAT: Grassland and plains to deciduous forest and high-altitude environments.

CONTEMPORARY RANGE: Widespread, now found in most tropical to warm temperate regions of the world. Found in much of California, except the northern third of the state and the most arid regions of the state.

FOUND WITHIN STUDY AREA: Growing within an unirrigated three-foot-wide median on Adeline Street.

LIKELY MEANS OF ARRIVAL TO STUDY AREA: Some form of human activity but specifc means not yet determined.



ESCHSCHOLZIA CALIFORNICA / CALIFORNIA POPPY

 

PROVENANCE/NATURAL RANGE: California, extending into Oregon, Washington, Nevada, Arizona, New Mexico, Sonora and northwest Baja California.

NATIVE HABITAT: Open and/or disturbed grasslands.

CONTEMPORARY RANGE: Natural range but also India, Chile, Argentina, Australia, and South Africa.

FOUND WITHIN STUDY AREA: Growing within an unirrigated three-foot-wide median on Adeline Street.

LIKELY MEANS OF ARRIVAL TO STUDY AREA: This plant is native to California and is a prolific self-sower. The seeds can be dispersed by wind, animals, or by way of people's shoes.



FESTUCA ARUNDINACEA / TALL FESCUE

 

PROVENANCE/NATURAL RANGE: Europe and east into Siberia, with some saying it is also native to North Africa.

NATIVE HABITAT: Damp grasslands, river banks, and coastal seashore locations.

CONTEMPORARY RANGE: Original range but now including much of the United States, particularly in the West and Southeast. Considered a noxious weed in coastal California.

FOUND WITHIN STUDY AREA: Growing within an unirrigated eight-foot-wide median on Adeline Street.

LIKELY MEANS OF ARRIVAL TO STUDY AREA: First appeared in seed catalogs in the US in 1870 as a forage grass.



HYPOCHAERIS RADICATA / CAT'S EAR

 

PROVENANCE/NATURAL RANGE: The oldest populations of Hypochaeris radicata have been found in Morocco. It then seems to have made its way to the southwestern Iberian Peninsula in the Late Quarternary (past .5 to 1.0 million years). It is now commonly considered native to the Mediterranean Basin.

NATIVE HABITAT: Most likely dry and open sites and spaces. Not likely to have grown in riparian environments.

CONTEMPORARY RANGE: Europe, the Americas, Japan, Australia, New Zealand, Southern Africa.

FOUND WITHIN STUDY AREA: Growing within an unirrigated three-foot-wide median on Adeline Street.

LIKELY MEANS OF ARRIVAL TO STUDY AREA: Human travel from Europe to the United States.



NASSELLA TENUISSIMA / MEXICAN FEATHER GRASS

 

PROVENANCE/NATURAL RANGE: Mountains of west Texas and southern New Mexico and south into central Mexico. A separate native population exists in southernmost South America in Argentina and Chile.

NATIVE HABITAT: Open woods on rocky flats and slopes with well-drained soils in the Trans-Pecos Mountains.

CONTEMPORARY RANGE: Original range in addition to Australia, New Zealand, South Africa, other parts of the western US. It is known to have naturalized in California, New Zealand, and South Africa.

FOUND WITHIN STUDY AREA: Growing in between the asphalt street surface and the edge of a concrete median along Adeline Street just across from the Ed Roberts Campus.

LIKELY MEANS OF ARRIVAL TO STUDY AREA: Introduced to the nursery trade. Each plant can produce 1,000s of seeds, which can readily self-sow in degraded and disturbed soil.



PASPALUM DILATATUM / DALLIS GRASS

 

PROVENANCE/NATURAL RANGE: Argentina, Bolivia, Brazil, Chile, Paraguay, and Uruguay.

NATIVE HABITAT: Moist grasslands at varying elevations that frequently experience both flooding and drought.

CONTEMPORARY RANGE: Original range in addition to subtropical regions of the US, and Australia, Africa, Portugal, Spain, Azores, Italy, Austria, Germany, Iran, Turkey, and India.

FOUND WITHIN STUDY AREA: Growing within an unirrigated three-foot-wide median on Adeline Street.

LIKELY MEANS OF ARRIVAL TO STUDY AREA: Introduced as a pasture grass. Its common name, dallis grass, was derived from T. A. Dallis, a 19th-century farmer who grew the species near La Grange, Georgia.



PLANTAGO LANCEOLATA / NARROWLEAF PLANTAIN

 

PROVENANCE/NATURAL RANGE: The oldest records show that it was endemic to Western Norway starting in the Early Neolithic era. However it is most commonly said to be endemic to Europe, North Africa, and West and South Asia

.

NATIVE HABITAT: Grasslands that are not excessively hot.

CONTEMPORARY RANGE: Original range in addition to every continental state of the US, as well as in Hawaii, Australia, New Zealand, Japan, and in many African countries, where it thrives at high altitudes. It is also found in Canada and Greenland.

FOUND WITHIN STUDY AREA: Growing within an unirrigated eight-foot-wide median on Adeline Street.

LIKELY MEANS OF ARRIVAL TO STUDY AREA: Human activity; specific means yet to be determined.



SONCHUS OLERACEUS / SOW THISTLE

 

PROVENANCE/NATURAL RANGE: Africa (Northern/Mediterranean region), temperate Asia (Middle East to China and Siberia), tropical Asia (northern India, Nepal, northern Pakistan), and Europe.

NATIVE HABITAT: Adapted to many environments, growing well at low to high elevations with varying levels of preciptation, within the tropics. As such, it is often referred to as a "cosmopolitan" plant.

CONTEMPORARY RANGE: Original range in addition to Australia (excepting the driest and northenrmost parts of the country), tropical and southern Africa, New Zealand, North America (i.e. the US, Canada, and Mexico), Central America, the Caribbean, South America, Mauritius, south-eastern Asia (i.e. Vietnam, the Philippines, Taiwan, and Papua New Guinea), and on several Pacific islands (i.e. the Gal pagos Islands, Fiji, French Polynesia, Guam, Hawaii, Kiribati, the Marshall Islands, New Caledonia, Niue, and Tonga).

FOUND WITHIN STUDY AREA: Growing within an unirrigated three-foot-wide median on Adeline Street.

LIKELY MEANS OF ARRIVAL TO STUDY AREA: Introduced as a source of food (the leaves are fully edible), as a medicinal plant, and as a pasture crop. It was found growing in California as early as 1824.
